Description

Technical Field

[0001] This application relates to the field of round bagging machine technology, and in particular to a dual compression chamber device for a round bagging machine with non-stop function and a round bagging machine. Background Technology

[0002] With the continuous optimization and upgrading of my country's agricultural industrial structure and the rapid development of animal husbandry, the demand for forage has shown a year-on-year increasing trend, and the resource utilization rate of crop straw has also steadily improved. Against this backdrop, the collection, storage, and transportation of straw and forage place higher demands on mechanized equipment. Currently, straw and forage harvesting operations in my country mainly use two types of equipment: square bale balers and round bale balers.

[0003] Existing round bale baling machines generally employ a single compression chamber structure, requiring a shutdown during operation to complete the wrapping and unloading processes. Specifically, when the compression chamber pressure reaches a preset threshold, the equipment must stop moving, simultaneously pausing the picking mechanism and activating the wrapping device. Only after the wrapping process is complete, the bale is released, and the compression chamber door is closed after the bale lands, allowing the next work cycle to begin. This intermittent operation mode results in relatively low equipment efficiency. Furthermore, traditional fixed-diameter round bale baling machines suffer from uneven bale density distribution, exhibiting a tight outer layer and a loose inner layer, leading to a low overall average bale density.

[0004] Therefore, it is necessary to design a dual compression chamber device for a round baggage machine with non-stop function to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a dual compression chamber device and round bag machine with non-stop function, which effectively solves the problem that the existing round bundling machines can only stop to perform the wrapping and unloading processes, and the bundling density is uneven.

The second compression chamber includes a third fastening part pivotally disposed at a second end of the main body. Materials enter the first compression chamber through the feeding mechanism and are initially packaged. The materials are then pivotally pushed into the second compression chamber by the first and second fastening parts to form bundles. The bundles are then transferred to a wrapping mechanism via the third fastening part.

[0008] Preferably, the top of the first fastening part and the third fastening part are respectively provided with a first winding mechanism and a second winding mechanism.

[0010] Preferably, a density control mechanism is provided on the side of the second fastening part away from the first fastening part. The density control mechanism includes a tightening spring, which abuts against the outer wall of the second fastening part. As the material inside the first compression chamber gradually increases, the tightening spring is gradually compressed by the second fastening part.

[0011] Preferably, the first fastening part and the second fastening part are connected by a connecting rod, the first end of the connecting rod is rotatably connected to the second fastening part, the second end of the connecting rod is provided with a sliding groove, and the first fastening part is slidably disposed in the sliding groove by a connecting member.

[0012] Preferably, the dual compression chamber device for the round bag machine with non-stop function can switch between an empty state, a pre-compression state, a transfer state, a post-compression state, and a discharge state; when the dual compression chamber device for the round bag machine with non-stop function is in the empty state, the pre-compression state, and the discharge state, the channel adjustment component faces the first feed inlet; when the dual compression chamber device for the round bag machine with non-stop function is in the transfer state and the post-compression state, the channel adjustment component faces the second feed inlet.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the embodiments of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to a first aspect of this utility model, a dual compression chamber device for a round baggage machine with non-stop function is provided, such as... Figures 1 to 8 As shown, the dual compression chamber device for a round bagging machine with non-stop function is used for collecting and baling materials such as straw or hay. The dual compression chamber device for a round bagging machine with non-stop function includes a main body 1 and a first compression chamber 2 and a second compression chamber 3 located on the main body 1.

[0026] In the following description, reference will be made to Figures 1 to 8 This section describes the detailed structure of the main body 1, the first compression chamber 2, and the second compression chamber 3 of the dual compression chamber device for a round baggage machine with non-stop function.

[0027] like Figure 1 As shown in the embodiment, the main body 1 can be understood as the frame structure of the device, used for the installation and connection of the first compression chamber 2, the second compression chamber 3, and the feeding mechanism 4. The device can also be installed on a round bagging machine via the main body 1. The shape of the main body 1 can be adjusted according to the specific structure and specifications of the round bagging machine; there are no restrictions here, as long as it can accommodate the first compression chamber 2, the second compression chamber 3, and the feeding mechanism 4, and fulfill the function of packaging materials.

[0028] Specifically, a first compression chamber 2 and a second compression chamber 3 are respectively provided at both ends of the main body 1. These two ends can be understood as... Figure 1 The left and right ends of the middle, due to Figure 1 This is a side view of the dual compression chamber device for the round bagging machine with non-stop operation. Therefore, from a top-down perspective, the first compression chamber 2 and the second compression chamber 3 can be located at the front and rear ends of the actual process, respectively. The first compression chamber 2 can be used for pre-compression and pre-wrapping, while the second compression chamber 3 can be used for compression and packaging. During the packaging operation, the second compression chamber 3 does not affect the first compression chamber 2 from performing pre-compression again.

[0029] Furthermore, a feeding mechanism 4 is provided at the bottom of the main body 1. The feeding mechanism 4 may include a pick-up device commonly used in existing round bagging machines for collecting materials, as well as conveying rollers and forming belts for conveying materials into the compression chamber. Since these components are commonly used in existing technologies and are known to those skilled in the art, their structural principles and installation methods will not be elaborated here. The feeding mechanism 4 can pick up and adjust the size of materials, and then convey the materials to the first compression chamber 2 and the second compression chamber 3. The internal structure of the first compression chamber 2 and the second compression chamber 3 can be the internal structure of the compression chamber of a common round bagging machine. For example, in the embodiment, the structure located inside the first compression chamber 2 (e.g., the conveying roller and the packing net feeding roller in the winding mechanism described below) can be fixedly installed inside the first fastening part 201, while the second fastening part 202 does not have a specific structure installed inside or only has a portion of the fixing rollers used to fix the forming belt installed to ensure smooth compression and packaging. However, it is not limited to this and can be specifically set as needed, which is not restricted here. The packaging and compression process of the round bag machine with non-stop function using a dual compression chamber device is the same as that in the prior art (for example, using a starting roller to form a bundle core of material, and then using a forming belt to form the bundle; the installation of the forming belt can be achieved by using multiple fixed transmission rollers to drive the material, and by using a hydraulic tension arm and other structures to press the bundle tightly against the forming belt so that the bundle can be compacted). These are all prior art, which can be known by those skilled in the art, and are not related to the core design points of this application. They can be found through the Internet or existing patent documents, so they will not be described in detail here.

[0030] The design of this non-stop round bag machine with dual compression chambers differs from existing compression chamber designs in that the material pre-treated in the first compression chamber 2 can be pushed into the interior of the second compression chamber 3. Specifically, the first compression chamber 2 may include a first fastening part 201 pivotally disposed at the first end of the main body 1 and a second fastening part 202 coaxial with the feeding mechanism 4. The first fastening part 201 can surround, as shown in the figure... Figure 2The first pivot 203 shown rotates, and the second fastening part 202 can rotate around as shown. Figure 2 The second rotating shaft 102 shown rotates, and the second rotating shaft 102 can also be the central shaft of the feeding assembly 401. Driven by the rotation of the first engaging part 201 and the second engaging part 202, the material located inside the first engaging part 201 and the second engaging part 202 is pushed into the second compression chamber 3. The second compression chamber 3 may include a third engaging part 301 pivotally disposed at the second end of the main body 1. The second compression chamber 3 can also be understood as being jointly formed by the main body 1 and the third engaging part 301, the third engaging part 301 being able to rotate around... Figure 2 The rotation of the third shaft 103, as shown, causes the bales formed in the second compression chamber 3 to be discharged. The core working principle of this non-stop round bag machine with a double compression chamber device is as follows: the material enters the first compression chamber 2 through the feeding mechanism 4 and is initially packaged. It is then pivotally pushed into the second compression chamber 3 by the first fastening part 201 and the second fastening part 202 to form a bale. The bale is then transferred to the wrapping mechanism 6 through the third fastening part 301. The wrapping mechanism 6 wraps the bale with film. After the process is completed, the bale is released, and at this point, one process is finished. Furthermore, since the material is pre-compressed in the first compression chamber 2, the initially formed bales have small mass and size. The forming pressure of the bales can be adjusted according to the small size and mass to ensure uniform density. The initially formed bales then enter the second compression chamber 3, where they gradually form larger bales with greater mass and size. Therefore, the forming pressure can also be adjusted according to the larger mass and size to ensure uniform density inside and outside the bales. This solves the problem of existing fixed-diameter round bale machines having a tight outer layer and a loose inner layer, resulting in a low average bale density. Additionally, the wrapping mechanism 6 can be a mechanism from existing technologies; its structure and principle will not be elaborated here.

[0031] This non-stop round bag machine with a dual compression chamber device, through the cooperation of the main body 1, the first compression chamber 2, and the second compression chamber 3, can achieve simultaneous operation of the two compression chambers. By utilizing the pre-treatment of the first compression chamber 2 in conjunction with the forming and bundling of the second compression chamber 3, the entire operation process can be carried out without stopping for picking, wrapping, and unloading, solving the problem of low equipment efficiency caused by the intermittent operation mode in the existing technology. In addition, by utilizing the secondary bundling operation of the first compression chamber 2 and the second compression chamber 3, the problem of low average density of the bundling caused by the tight outer and loose inner density of the existing fixed diameter round bag machine is solved.

[0032] Preferably, such as Figure 4As shown, in the embodiment, the end of the main body 1 facing the first compression chamber 2 is provided with a transfer port 101. The inner wall of the first fastening part 201 can abut against the inner wall of the second fastening part 202, so that the second fastening part 202 can surround the first fastening part 201. The outer wall of the first fastening part 201 can abut against the transfer port 101 to separate the first compression chamber 2 and the second compression chamber 3.

[0033] Preferably, such as Figures 1 to 5 As shown in the embodiment, the tops of the first fastening part 201 and the third fastening part 301 are respectively provided with a first winding mechanism 501 and a second winding mechanism 502. The first winding mechanism 501 can perform a pre-winding process on the material inside the first compression chamber 2, and the second winding mechanism 502 can perform a winding process on the bundles inside the second compression chamber 3. In the first compression chamber 2, in order to ensure the forming density and quality of the pre-compressed bundles, the first winding mechanism 501 can be used to wind the pre-compressed bundles. Or, if the material is small, it is also necessary to pre-set the first winding mechanism 501 to wind the bundles in the first compression chamber 2. However, if the pre-compressed bundles do not need to be wound, the operation of the first winding mechanism 501 can be canceled. In addition, it should be noted that the first wrapping mechanism 501 and the second wrapping mechanism 502 can both be commonly used wrapping mechanisms in the prior art (e.g., including actuators, mesh packaging systems and packing mesh feed rollers, etc., which contact the formed bundles through the packing mesh feed rollers and cooperate with the forming belt in the compression chamber to wrap the bundles). The wrapping mechanism and wrapping process are known to those skilled in the art, and their cooperation structure with the compression chamber is also a common structure, which will not be described in detail here.

[0034] Preferably, such as Figures 1 to 5 As shown, in this embodiment, the ends of the first compression chamber 2 and the second compression chamber 3 facing the feeding mechanism 4 are provided with a first feed inlet and a second feed inlet (due to...). Figures 1 to 5 This is a side view, therefore the first and second feed inlets are not shown. The first feed inlet may be the end of the first fastening part 201 near the feeding mechanism 4, and the second feed inlet may be the bottom of the main body 1 near the feeding mechanism 4. The feeding mechanism 4 may include a feeding assembly 401 and a channel adjustment assembly 402. The feeding assembly 401 may be, for example, the pick-up device described above, for picking up materials. The channel adjustment assembly 402 is adjustablely positioned on the side of the feeding assembly 401 so that materials enter the first or second feed inlet through the feeding assembly 401. The channel adjustment assembly 402 may include an H-shaped structure (to... Figure 1(As shown in the side view) multiple plates, one of the two vertical plates of the H-shaped structure is coaxial with the second rotating shaft 102. The two vertical plates of the H-shaped structure can be driven by the horizontal plate to move towards the first feed port or the second feed port, thereby causing the material entering from the feeding assembly 401 to move to the first feed port or the second feed port.

[0035] Preferably, such as Figures 1 to 5 As shown, in this embodiment, a density control mechanism is provided on the side of the second engaging portion 202 away from the first engaging portion 201. The density control mechanism may include a clamping spring 7, which abuts against the outer wall of the second engaging portion 202. As the material inside the first compression chamber 2 gradually increases, the clamping spring 7 is gradually compressed by the second engaging portion 202. The density control mechanism may also include a positioning seat for fixing the clamping spring 7. The positioning seat may be fixedly installed on the main body 1, for example, in the form of a fastening bolt and nut. The clamping spring 7 is disposed at the end of the fastening bolt.

[0036] Preferably, such as Figure 4 As shown in the embodiment, to ensure stable movement, the first engaging part 201 and the second engaging part 202 are connected by a connecting rod 8. The first end of the connecting rod 8 is rotatably connected to the second engaging part 202, and the second end of the connecting rod 8 has a sliding groove. The first engaging part 201 is slidably disposed in the sliding groove via a connecting member 9. Both ends of the connecting rod 8 can be connected to the first engaging part 201 and the second engaging part 202 via the connecting member 9, which can be, for example, a pin.

[0037] Furthermore, such as Figures 6 to 8 As shown, in this embodiment, the dual compression chamber device for the round bag machine with non-stop function may further include a sensor 10 and a user interface 11. The user interface 11 detects the distance between itself and the outer wall of the second fastening part 202, i.e., the second gap 12, through the sensor 10. The sensor 10 may be, for example, a distance sensor, and the user interface 11 may be, for example, a display screen in the cab of the round bag machine. The length of the second gap 12 can provide feedback on the current state inside the first compression chamber 2, and the user can understand the state inside the first compression chamber 2 through the user interface 11.

[0038] The specific working process of the dual compression chamber device for the round baggage machine with non-stop function is as follows: Preferably, as follows: Figures 1 to 5 As shown in the embodiment, the dual compression chamber device for the round bag machine with non-stop function can switch between an empty state, a pre-compression state, a transfer state, a post-compression state, and a discharge state. The empty state is as follows: Figure 2 As shown, the pre-compression state is as follows Figure 3 As shown, the transition state is as follows Figure 4 As shown, the discharge status is as follows Figure 5As shown, the difference between the rear compression state and the front compression state lies in the orientation of the channel adjustment component 402. Specifically, when the dual compression chamber device for the round bag machine with non-stop function is in the empty state, the front compression state, and the discharge state, the channel adjustment component 402 faces the first feed inlet; when the dual compression chamber device for the round bag machine with non-stop function is in the transfer state and the rear compression state, the channel adjustment component 402 faces the second feed inlet.

[0039] Preferably, such as Figure 2 As shown, in the embodiment, when the dual compression chamber device for the round bag machine with non-stop function is in an empty state, the first fastening part 201 fastens to the second fastening part 202, and the third fastening part 301 fastens to the end of the main body 1 facing away from the first compression chamber 2; at this time, the first gap 204 between the first fastening part 201 and the second fastening part 202 is empty (or can be understood as having no gap), and there is a second gap 12 between the second fastening part 202 and the sensor 10 (e.g., Figure 6 As shown), the length of the second gap 12 is calibrated to the zero position, and the user can see through the user interface 11 that the first compression chamber 2 is empty and no pressure is applied to the bale. At this time, the feed port of the channel adjustment component 402 is connected to the first feed port.

[0040] Preferably, such as Figure 3 As shown, in this embodiment, when the dual compression chamber device for the round bag machine with non-stop function is in the pre-compression state, the first fastening part 201 and the second fastening part 202 gradually separate. At this time, the bundle inside the first compression chamber 2 gradually increases in size, causing the first fastening part 201 and the second fastening part 202 to gradually separate. The second fastening part 202 rotates counterclockwise around the second rotating shaft 102, and the clamping spring 7 is gradually compressed. Figure 7 As shown, the second gap 12 gradually decreases until it reaches a set value. At this point, the sensor 10 receives a signal, causing the channel adjustment component 402 to change position and align the feeding port with the second inlet. Simultaneously, the first wrapping mechanism 501 begins pre-wrapping the bales inside the first compression chamber 2. The pre-wrapping can be activated or deactivated as needed.

[0041] Preferably, such as Figure 4As shown, in the embodiment, when the dual compression chamber device for the round bag machine with non-stop function is in the transfer state, the first fastening part 201 separates from the second fastening part 202, and the third fastening part 301 fastens to the end of the main body 1 facing away from the first compression chamber 2. After the pressure in the first compression chamber 2 reaches the set value, the sensor 10 receives a signal, tightens the spring 7 to release the pressure, and can give the second fastening part 202 an initial pushing force, so that the bundle is transferred. The first fastening part 201 can then open upward under the drive of the hydraulic cylinder (not shown, which can be set in the main body 1), driving the connecting rod 8 to move. The connecting rod 8 pulls the first fastening part 201 to rotate clockwise around the second rotating shaft 102, pushing the bundle into the interior of the second compression chamber 3. At this time, the second gap 12 is relatively large (e.g., Figure 8 As shown), the user can receive information through the user interface 11 that the first compression chamber 2 is in an open state or the current transmission position.

[0042] Preferably, such as Figure 5 As shown in the embodiment, when the dual compression chamber device for the round bag machine with non-stop function is in the discharge state, the first fastening part 201 fastens to the second fastening part 202, and the third fastening part 301 separates from the main body 1. As the material increases, the pressure value inside the second compression chamber 3 also increases. After the gap between the third fastening part 301 and the main body 1 reaches a certain distance, the sensor 10 will receive a signal, the channel adjustment component 402 will connect the feeding port with the first feeding port, the second wrapping mechanism 502 will wrap the formed bundle with netting, after the wrapping is completed, the third fastening part 301 will rotate counterclockwise around the third rotating shaft 103, the bundle will roll onto the wrapping mechanism 6, then the third fastening part 301 will close, the wrapping mechanism 6 will wrap the bundle with film, and after the process is completed, the bundle will be released. At this time, one cycle ends, and the machine does not stop during the entire process.

[0043] This non-stop round bag machine with a dual compression chamber device, through the cooperation of the main body, the first compression chamber, and the second compression chamber, can achieve simultaneous operation of the two compression chambers. By utilizing the pre-treatment of the first compression chamber in conjunction with the forming and bundling of the second compression chamber, the entire operation process can be carried out without stopping for picking, wrapping, and unloading, solving the problem of low equipment efficiency caused by the intermittent operation mode in the existing technology. In addition, by utilizing the secondary bundling operation of the first and second compression chambers, the problem of low average density of the buns caused by the tight outer and loose inner bundling density of the existing fixed diameter round bag machines is solved.

[0044] Furthermore, according to a second aspect of the present invention, a round bagging machine is provided, the round bagging machine including the double compression chamber device for a round bagging machine with non-stop function as described above.

[0045] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
